Robotic versus laparoscopic anti-reflux and hiatal surgery in a uk benign upper gi unit: perioperative outcomes in a four-year observational study.
Observational study in Journal of robotic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Robotic fundoplication is rapidly expanding across the UK, however, robust comparative data from routine benign upper gastrointestinal (UGI) practice remain limited. This study compares perioperative outcomes of robotic and laparoscopic fundoplication within a UK benign UGI unit. This retrospective observational study included consecutive adults undergoing elective laparoscopic or robotic anti-reflux or hiatal surgery between February 2022 and January 2026. The primary outcome was total operative time. Secondary outcomes included length of stay, same-day discharge, complications, 30-day readmission, 30-day return to theatre, subsequent redofundoplication and early clinically recorded recurrence. One hundred patients were included: 57 robotic and 43 laparoscopic. Revisional surgery was more frequent robotically (33.3% versus 11.6%; p = 0.006). Overall, robotic procedures had shorter median operative times (88 versus 120 min; p = 0.017) and higher same-day discharge rates (63.2% versus 27.9%). After excluding the highest-volume robotic surgeon, median robotic operative time remained 27 min shorter than laparoscopy (93 versus 120 min), although the difference was no longer statistically significant (p = 0.16). Among 76 primary operations, robotics was associated with shorter unadjusted operative time (77 versus 120 min; p < 0.001), shorter length of stay (0 versus 1 day; p = 0.003) and higher same-day discharge (60.5% versus 23.7%; OR 4.94, 95% CI 1.83-13.31; p = 0.002). Following covariate adjustment, operative time remained an estimated 11% shorter robotically, although the confidence interval included no difference (time ratio 0.89, 95% CI 0.72-1.09; p = 0.250). The association with same-day discharge persisted after adjustment (OR 5.02, 95% CI 1.09-23.00; p = 0.038). Robotic anti-reflux and hiatal surgery was successfully integrated into an established benign UGI service, including for a substantial revisional workload. Favourable operative times and same-day discharge rates demonstrate the potential for efficient service delivery, although the respective contributions of platform, surgeon expertise, case selection and treatment era cannot be separated. These findings demonstrate feasibility and support further prospective evaluation of its comparative clinical and economic value.
